6 Claims. (Cl. 282-20) vThis invention relates to a carbon holderfor.awriting machine and: more. particularly to a holder. fora. carbon"roll in an autographic register which permits quick change of "the.carbon.

.Autographic registers have been'used for some time -:and some have beenequipped with .a roll of .carbon which runs. crosswise ofthewritingplaten. These regisrterswere so constructed thatit wasnecessary to open the aregister inorderzto change the carbon. .That.also necessitated the handling .of: thecarbon so.that smudgesoften werea. necessary part of the carbonchanging .as the material. hadto. .behandled by hand.

In .contrast with the most .usual register structures, the presentdevice.has thercarbon extending from arollsupply .over. the -platen in: thesame direction .as -the. stationery. .Whenit. is..desired..to -changetthe writing .surface of.the ..carhon.strip,-.no..opening. oftheregisteris required. and -nowhandlingof the carbonmaterialis.-necessary. .The [change .may. be efiected quickly .-and very.easily.

.;It.is,- therefore, .the .principal object of .the .present. inatention.to .provide .a .new mechanism .,for -holding .and changing. carbonin awriting .machine.

A .further. object .is to -provide. a. .means Jfor changing carbon in anautographic register without thenecessity of opening .the. registertoetlect the .change.

'Another .objectlis .to; provide ..a structure .for. changing .ca'rbonin .an autographic register which requiresuno actu'al' haridlingof the.carbon material.

Other objects, features :and. advantages of the present invention willbe obvious from thefollowing description of apreferredembodiment takenin. conjunction with the accompanying drawings .in 1 which:

The lower stationery. strip 20 passes from the .supply 'directly oventheplaten-16. .The .carbon holders are position'e'dsidebysideandtextendacross.the register on the .rears'ideof the,.platen. -Each holder istrna'de to receive .a' carbon rdllR.so-,that-a-strip ofrcarbon material may be placed over {the .platenbetween each. of the record stationery strips. Thus, the .neXtstrip21-.extends around the first holder and then over theplatentso.that-thecarbon strip S will be interposed between. the firstrecord-stnipZl) and second strip 21. In the particular aembodimentshown, .four stationery strips ,passover the platen and three carbonstrips are interleaved with .therecord strips.

The superposed strips maypass undera guide bladeitl on one side of theplaten "while a pin type feed; may engage perforations .in a feed bandon the .oppositesiderofthe stationery strips. The carbonstripsarenarrower than thestationery by an amount.equalto-thetwidthofthe is not engaged vby the feed-pins.

The structure vof each .carbon holderissuchihat it "holds a roll ofcarbon material against advancement over "the platen when thestationery'is. advanced by. the feeding means inthe register. When thecarbon becomesworn so that it "shouldbe replaced, a mechanism isprov.ided;to

permit the rolls'to' turn in the holdersallowing fthe.ea'rbon to feedthrough the register and over. theplaten withthe stationery strips. 50

The'particular structure of thelholder which; permits 'this functionisone of simple but effective design. -Each holder'has a rounded body 39secured by detents 31in a'left-hand end plate 32 and "by similar detents33 in a right-hand end plate 34. .Thefrounded body'30 .comprisesa..semicircle in cross section southat the forwardly facing portion ofthe body isyopen.

The end,plate '32 isprovided with .an aperture 35 connected to theforward edge 36 of the. plate by..a vslot 37 slightly narrower thanthe.opening. Outwardly extending ears 38 at the lower edges -.oftheplateaserve to support the left=hand end .of theholderonaplat- .form39. ..A stop 40.at.the rear oftheplattormr39.holds .all .of the.platesin. abutting-side .by.-side position .be-

tween the stop and .the rearportion 41 supporting :the

. platen.

The. opposite end platesi34 .are .formed witha central aperture '42.These plates are :provided on=their aseenss ister so that each holdermay be swung upwardly as indicated in the dotted lines of Figure 3.

The carbon roll R is held in the holder on a spindle 46 having a bluntend 47 for insertion through the aperture 42 in the right-hand endplates 34. A thimble 48 1s shdingly mounted on the opposite end of thespindle and held against removal by a screw 49. The thimble is urgedtoward the end of the spindle by a compression spring 50 connected tothe spindle.

The spring 50 aids in retaining the spindle in the holder when a roll ofcarbon is placed on the spindle. Each spindle has a disk 51 spaced fromthe opposite end plate 34 a distance such that it will be in contactwith the roll when the spindle is placed in the holder. Thus, a carbonroll equipped with a core 52 may be passed over enlarged portions 53 onthe spindle and then the spindle may be inserted in the holder byplacing the blunt end 47 in the aperture 42, bringing the end of theroll into contact with the end plate 34. By contmuing this movementafter the contact of the roll and the plate, the spring 50 may becompressed moving the spindle through the roll until the disk 51 hitsthe opposite end. At this point, the thimble cannot be passed throughthe slot 37 because it is too wide at the point which would strike theopening to the slot. However, the thimble is slidingly mounted so thatupon further compression of the spring 50, the narrow portion 54 of thethimble may be aligned with the slot so as to pass through the slot andinto the enlarged openmg 35. Thereafter, the spring 50 urges the thimbleoutwardly and maintains the spindle in a position to hold the disk 51against the end of the carbon roll. By this simple structure, the singlespring 50 can serve to hold the spindle in the holder and alsofrictionally bind the roll against turning on the spindle. I When thecarbon becomes worn to an extent that it should be changed, the operatorof the register need only release the tension of the disks against therolls so that they may turn, allowing the carbon to move forwardly withthe stationery over the platen. A simple mechanism mounted in the lid 12is provided to accomplish this purpose. A thumb piece 55 is connected toa cam shaft 56 upon which is mounted a plurality of cams 57, oneopposite each spindle. Upon turning of the shaft, the cams come incontact with the blunt ends 47 of the spindles, moving them to the leftin the holders, thus compressing the spring 50 and moving the disks 51away from the rolls as illustrated in Figure 8. Coil spring 58 urges thecam shaft to a position of rest, holding the cams away from thespindles, however, the cams will stay in contact with the spindleswithout manually holding the thumb piece, due to the illustrated shapeof the cams. A small detent 59 on the underside of the finger piece 55may travel in an arcuate slot 6% in the casing to limit turning movementof the thumb piece and shaft 56.

When the carbon rolls are released from the frictional holdingaccomplished by the disks on the spindles, the friction between thesuperposed carbon strips and stationery strips may be enough to pull thecarbon forwardly and discharge a form length from the register. Shouldthis friction between the strips be insufficient, slight hand pressurecan be placed by the operator on the superposed strips in the area overthe platen to insure that the carbon is advanced with the stationery. Ifdesired, suitable mechanical means may be provided for applying thelight pressure in place of hand pressure. When a form length is tornfrom the strips, the carbon strips are likewise severed and may bediscarded. A new sheet of carbon will be maintained in place by areverse rotation of the thumb piece 55 to again pp y the tension andfriction hold on the carbon rolls. The structure is particularlyeffective in that rolls of carbon of approximately 40 ft. in length canbe suppliedso 4 that the carbon need only be replenished after extendeduse.

The form of the carbon holders is such that the body provides a verygood guide for leading the stationery strips around each holder. Verylittle chance of difficulty is presented by the structure.

While I have shown and described certain embodiments of my invention, itis to be understood that it is capable of many modifications; Changes,therefore, in the construction and arrangement may be made withoutdeparting from the spirit and scope of the invention as disclosed in theappended claims.
